Standing around in an X singing? Fuck off
And they're stingy, back when I was dirt poor they'd charge me a quid a day for being in my overdraught (30 quid a month could've sunk me if I wasn't living at home). So yeah I'm not a fan just too lazy to switch.

Post Office Savings - Birth to now (basically empty since 14 when I put it all toward a school ski trip).
Lloyds - From first non cash- in-hand job at 16 until the end of the first year at uni when they wouldn't let me have an overdraft. So I chinned 'em off.
Midland, NatWest, and Barclays - Opened an account with 'em all before going to uni to scoop up the free shit. Bought my very first PC with the generous HSBC no questions asked overdraft. NatWest were a shower of shit. Barclays were ok. All accounts were opened before online banking existed. And when it got introduced it was fucking shit. So I closed them all when I graduated, then moved to...
Smile - who did the online thing properly and I'm still with 'em more than a decade later and would defo recommend them. Their online interface has barely changed in well over a decade. Retro online banking! But even though it reeks of 90s internet to look at, it's pretty much perfect functionally.
Have had Barclaycard and Virgin credit cards for some 0% interest balance transfer japes.
Had a loan with Northern Rock. Then they went titsup.
Mortgage is with Yorkshire Building Society. They've been good.

Think I still might have 40 odd quid stashed away there. I'll never get it out - you probably still need that paying in book which is long gone.

Nat West since about 11.
That's it. Had all those piggy bank things as well. Think they got binned - probably worth loads now.
I like them - they let me off all the fees I've ever incurred - plus you get to chat to some rad scottish guys and girls when you call them up.

Opened a metro bank account for when I was travelling - never touched it since.
